3.6.5
The inverter with PROFINET interface as Ethernet node.
As default setting, the inverter is set for PROFINET IO communication. Alternatively, you
have the option of integrating the inverter into an Ethernet network via the PROFINET
interface.
This means that from any location in a network, you can use Startdrive to make diagnostic
queries, change parameters or carry out commissioning work.
PROFINET I/O communication is not possible with the inverter as Ethernet node.
Integrating an inverter into an Ethernet network (assigning an IP address)
Procedure
1. Set p8924 (PN DHCP mode) = 2 oder 3
– p8924 = 2: The DHCP server assigns the IP address based on the MAC address of
the inverter.
– p8924 = 3: The DHCP server assigns the IP address based on the device name of the
inverter.
2. Save the settings with p8925 = 2. The next time that the inverter switches on, it retrieves
the IP address, and you can address the inverter as Ethernet node.
Note
Immediate switchover without restart
The switchover to DHCP is performed immediately and without a restart if the change is
carried out with the Ethernet/IP command "Set Attribute Single" (class F5 hex, attribute
3). The following options are available:
•
via an Ethernet/IP controller
•
via an Ethernet/IP commissioning tool
You have now integrated the inverter into Ethernet.
